Disable NR for edxapp

[robrap]

Blockers:

• Disabling NR APM causes trace concatenation in Datadog #692 (tracing issue)
• Ensure Kafka Event Bus APM monitoring #658 (kafka monitoring)
  • I guess this isn't a blocker, but we should correct this blindspot sooner rather than later.

Acceptance Criteria:

• NR disabled for all of edxapp
  • LMS
  • CMS
  • LMS Workers
  • CMS Workers
  • Kafka Consumer in k8s
• Remove other old New Relic config/code, or ticket the removal
  • https://github.com/edx/edx-internal/pull/11757
  • feat: Remove New Relic support in edxapp role configuration#77
  • Remove newrelic as a dependency of edx-platform (probably a DEPR, and needs review of code references first) -- filed Remove newrelic from edx-platform dependencies #829

@robrap is this worth assigning to yourself or Tim and moving to IN PROGRESS? I believe at least some of these are checked off now...

@jristau1984: think this is blocked on the DD ticket marked in the description. We have removed the cost, but we haven't actually been able to remove NR and the performance impact and code, etc.

[jristau1984]

Moving to backlog to declutter the blocked column. This will not be able to be picked up until at least concatenation issue is resolved with DD support.

[jristau1984]

Marking this as "P2" priority, due to the fact that we are still incurring at ~20% performance impact from having both instrumentations active at the same time.

When this becomes unblocked, we should prioritize it immediately.

@jristau1984: I moved back from Blocked to Backlog, and put it in the new Post-New Relic epic that denotes that all its tickets are blocked.
